It Will thus be seen that I have provided a simpleand efficient device for accomplishing the objects herein set forth.

It is to be understood that the form ,of

my invention herewith shown and described 6 is to be taken as a preferred example of the same, and that various changes relative to the shape, size, materlal and arrangement of parts may be resorted -to Withoutdeparting from the spirit of the invention or the scope of-t'lre subj 'oi nedolainn I I r 7 Having thus described my invent'ion l claimze I V In a device of the character described :a

tank, a blower positioned adjacent said tank,

a measuring cup positioned adjacent said tank and said' bjlow'er, a pipe extending from said-measuring cup tosa'id tan-k, 'a-va lve positioned Within said pipe, a pipe extending from said measuring cup to said blower; ia valve "positioned within said last' mentioned pipe, means for rotating said blower for the purpose of: forcing theproducts of said blower and said tank to aremote point.
